DTC P0716: Problem in Input Shaft
(Mainshaft) Speed Sensor Circuit
NOTE:
• Record all freeze data and review General
T r o u b l e s h o o t i n g Information (see page 14-4) before
y o u troubleshoot.
• This code is caused by an electrical circuit p r o b l e m
and cannot be caused by a mechanical p r o b l e m in the
transmission.
1. Record all freeze data, and clear the DTC w i t h the
HDS.
2. Check for proper input shaft (mainshaft) speed
sensor installation (see page 14-223).
3. Raise the front of the vehicle, or lift the vehicle up,
make sure it is securely supported, and allow the
front wheels to rotate freely.
4. Start the engine, run the vehicle in the D position,
and hold the vehicle at speeds over 30 m p h
(48 km/h) for more than 10 seconds. S l o w d o w n
and stop the wheels.
5. M o n i t o r the OBD status for P0716 in the DTCs/
Freeze Data in A/T Mode Menu for a pass/fail.
Does the result indicate a fail?
Y E S — G o to step 6.
NO—Intermittent failure, the system is OK at this
t i m e . Check for loose or poor connections at the
PCM and the input shaft (mainshaft) speed sensor
connectors. If the tester indicates NOT COMPLETE,
return to step 4 and r e c h e c k . •
6. Turn the ignition switch OFF.
7. J u m p the SCS line w i t h the HDS.
8. Disconnect PCM connectors A (31P) and D (17P),
and the input shaft (mainshaft) speed sensor
connector.
9. Check for continuity between PCM connector
terminals A3 and body g r o u n d , and between D16
and body g r o u n d .

Is there continuity?
Y E S — G o t o step 10.
NO—Repair an open in the wires between PCM
connector terminals A 3 , D16, and ground (G101,
G102), or repair a poor g r o u n d (G101, G102), then
go to step 3 1 .
10. Connect PCM connectors A (31P) and D (17P).
11. Turn the ignition switch ON (II).
12. Measure the voltage between input shaft
(mainshaft) speed sensor connector terminal No. 1
and body g r o u n d .
